pdf text extractor in java

**Requirements** Develop a java based text extractor api for pdf documents. The most important requirement is performance. All code must be in java. An average 5MB pdf file must be parsed in an average of 5 seconds or less. The extracted text is to be used to building a search index so the resulting text need not be formatted at all. The UTF-8 , ISO-8859-1 (Latin-1) character sets must be supported. All pdf format versions existing to date must be supported. The solution must be "piped", i.e. the extractor must write to a pipe (both java reader and stream supported) as the text is being extracted. **Suggested Approach** Most open soure solutions first parse the pdf document and store it internally. Then they use the internal representation to extract the text. For text extraction purposes an internal rep. is not needed so the two steps can be merged, which will result in greatere efficiency. Another way to improve performance might be to parse different chunks of the document asynchronously repeicing as results become available, although this will make things very complex. ## Deliverables Rent A Coder requirements notice: As originally posted, this bid request does not have complete details.
